张家口地区属典型的半干旱地区,当地盛产黑柴胡(北柴胡),品质优良,在国内、外市场享有盛誉。近年来,随着医学研究的发展,柴胡的用量急剧增加,单靠采挖野生资源已不能满足社会市场的需求。1985—1991年,张家口地区坝下农科所与医药部门合作,进行了半干旱地区柴胡野生变家种试验研究并获得成功,基本上掌握了柴胡的生态环境要求及生物特性,初步摸清了柴胡的繁殖与人工栽培技术,并在荒坡、荒地示范500亩,取得了可观经济效益,每亩平均纯收入500多元。药检所分析测定,人工栽培的柴胡质量优于野生产品,其栽培技术要 Zhangjiakou area is a typical semi-arid area, the local rich black Bupleurum (North Bupleurum), good quality, reputation in the domestic and foreign markets. In recent years, with the development of medical research, the dosage of Bupleurum has rapidly increased. The excavation of wild resources alone can no longer meet the needs of the social market. 1985-1991, Zhangjiakou area under the agrochemicals under the cooperation with the pharmaceutical sector, carried out a semi-arid Zhacao wild changes in the pilot study and success, basically mastered the ecological requirements and biological characteristics of Bupleurum, the initial touch Clear Bupleurum breeding and artificial cultivation techniques, and in the slopes, wasteland demonstration 500 acres and achieved considerable economic benefits, the average net income per acre more than 500 yuan. Drug test analysis, artificial cultivation of Bupleurum quality is superior to wild products, its cultivation techniques
